Sea and Sky in St Helena

St Helena places much emphasis on its marine environmental monitoring. Regular seabird data, marine sighting reports and even some species of fish tagging are carried out through the year to gain better insight into the health of our waters. Coastal clean ups also regularly take place with volunteers keen to participate in such a community activity. 

Whether its wreck diving, sitting under the impeccable sub-tropic night sky where astronomer legends like Halley and Maskelyne mapped and documented significant findings, or hiking some of the most outrageously beautiful scenery on the planet – St Helena is a wonderful destination. 

The rich waters surrounding St Helena support a diverse array of marine life including many endemic species of fish, and the charismatic migratory Whale Shark, Humpback whale, and hawksbill turtle.

During the summer months, particularly January and February, the magnificent whale sharks are drawn to the island.  Strictly regulated, interactions with these magnificent beasts are a huge attraction for visitors, but it is the scientific interest that makes St Helenian encounters all the more unique. Being the only known place in the world to have equal ratio of male and female adults, researchers believe St Helena to be a key to the whale shark mating cycle.
